Launcher shim for the Python 3.11+ requirement — the version gate fires per invocation #44

Description

@mlava

Symptom

ringer.py needs Python 3.11+ (tomllib), but the shebang is #!/usr/bin/env python3 — on a stock Mac that's 3.9.6, so ./ringer.py <anything> fails with the version message every time, and every operator/wrapper has to remember the full interpreter path (/opt/homebrew/bin/python3.13 ./ringer.py ...). In the field this failed ./ringer.py hud mid-orchestration and the correct interpreter had to be rediscovered from a note (2026-07-14).

Proposed fix

Any of:

  1. a ringer launcher shim that probes python3.13 → python3.12 → python3.11 and execs the first that satisfies the gate,
  2. an install step (make install or a bootstrap script) that writes the resolved interpreter into a shim, or
  3. documented uv run support (uv resolves the interpreter from a pinned requires-python).

The version check itself is good — the ask is that the operator only pays for it once, not per command.
